  2. 6. Development of robust cyanobacterial strains for biotechnological applications : Stress tolerance and cell-specific expression in heterocyst-forming cyanobacteria

    Author : Xin Li; Karin Stensjö; Yagut Allahverdiyeva-Rinne; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Dps protein; heterocysts; Nostoc; oxidative stress; cell specific promoter; ROS tolerance; synthetic biology tools transcriptional regulation.; Biokemi; Biochemistry;

    Abstract : Synthetic biology tools can be used to exploit potential applications of cyanobacteria, promising photosynthetic hosts for production of fuels and chemicals. Specific genetic tools are needed for the development of robust cyanobacterial strains for bioengineering. READ MORE

  4. 7. Cyanobacteria in symbiosis with plants : Protein patterns and regulatory mechanisms

    Author : Martin Ekman; Birgitta Bergman; Dave G. Adams; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; symbiosis; Nostoc; Gunnera; Azolla; nitrogenase; modification; heterotrophic; proteomics; unsequenced; Plant physiology; Växtfysiologi;

    Abstract : Cyanobacteria belonging to the heterocystous genus Nostoc, capable of oxygenic photosynthesis and nitrogen fixation via the enzyme nitrogenase, may form symbiotic associations with plants. In these associations most of the N2 fixed by the symbiotic cyanobacteria (cyanobiont) is transferred to the host, which in turn supplies the cyanobiont with fixed carbon. READ MORE

  6. 9. Developmental patterns in the Nostoc-Gunnera symbiosis

    Author : Erik Söderbäck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Gunneraceae is an angiosperm family comprising about 60 species scattered in the southern hemisphere. All members of the family develop a nitrogen-fixing symbiosis with intracellularly located Nostoc. The aim of the present study was to characterize the symbiosis, structurally and physiologically, with emphasis on G. magellanica and G. READ MORE

  7. 10. Proteomic profiles and gene expressions in the symbiotically competent cyanobacterium Nostoc sp. PCC 73102

    Author : Liang Ran; Birgitta Bergman; Karl Forchhammer; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nostoc PCC 73102; hormogonia; 2-DE; symbiosis; photo-autotrophy; heterotrophy; cell differentiation; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : Nostoc PCC 73102 is an evolutionary important cyanobacterium with multiple phenotypic traits and symbiotic capacities. Based on two-dimensional gel electrophoresis (2-DE) and MALDI-TOF mass spectrometry, a proteomic approach was developed in order to obtain protein profiles of this symbiotically competent cyanobacterium during three trophic types/life stages: free-living photo-autotrophic and diazotrophic growth conditions, dark heterotrophic conditions and hormogonium formation.
